My definition of an individual human being, is when he can sustain his own life with his own organs.

Go underwater and sustain your life with your own organs.

Or in to a room with no oxygen.

Can't do it? Hm, you must not be human.

Go underwater and sustain your life with your own organs.

Easy - first I use my brain to figure out how to breathe underwater - aha SCUBA gear, then I don SCUBA gear and go underwater.

I guess you don't believe in using your brain.

and how do I, as an embryo, sustain my life?

if I am a born baby, and I am hungry, I skwall and cry, and attract the attention of my Mother to take care of me - that works.
